Fig.4 2 is a similar section through the lower end of the machine, showing the position of the parts during the descent of the plunger. Fig. 3 is a cross section on line 3, 3, Fig. l. Figs. 4, 5, 6, 7 and 8 are longitudinalsections through various forms of nozzles. Fig. 9 is a plan of Fig. 8, and Fig. lO a cross section on line 10, 10, Fig. 8. p

The letter a, represents the hopper or body` of my improved cake machine adapted for the reception of cream, jelly, dough, or other inaterial to be formed or embodied into a cake or article of confectionery. The hopper a, is contracted at its'lower end, as at a', to form a cylindrical chamber having one or more nipples a2, to which the discharge tube or tubes b are removably attached. Within the hopper a, there is free to reciprocate a central tubular plunger c, provided at its lower end with a iixed disk or collar c. To the lower end of the plunger c, there is furthermore secured an independently movable open head c2, (Fig. 3,) that is connected to the collar c', by headed guide pins c3. These pins are rigidly connected to the head c2, while they pass loosely through the collar c', and thus the head is free to move toward and away from the collar. A stem c4, projecting upwardly from the head c2, and 'into the bore of the plunger c, serves to properly guide the head o2, in its independent motion.

The upper end of the plunger c, passes through a spider a3, and is surrounded beneath its knob c5, by a coiled spring c6, that has a tendency to raise the plunger. Upon the knob c5, cup-shaped weights c7, of different sizes may be supported, which, when ap- `drical extension a.

plied, will contract the spring and force the plunger downward.` -In order to limit and 'regulate the throw of the plunger, it is provided with astop nut o8, that strikes the spider a2, when in its uppermost position, and thus checks the further ascent of the plunger.

yAs thus far described, the machine operates as follows: The hopper is lled with cream, dough, or other material, which Will flow through the open head c2, and into the cylin- The plunger is then slowly depressed, either by the weight c7, or by hand. This pressure will cause the disk c', to come into direct contact with the upper side of the open head o2, because the descent of the latter is checked by the resistance of the cream beneath it. ln this way the disk c', will close the openings of the head c2, and the parts c', c?, will jointly constitute one solid piston head, that will force the cream out of the tube b. When the plunger has arrived at the end of its 'downstroke, it is released (or the weight c7, is taken off) so that the spring c, is free to draw the plunger upward. During this motion, the disk c', will be moved o the head c2, and thus the openings in the latter will be exposed, and the cream will be free to enter the cylindrical extension a. As a general result therefore, the cylindrical extension will be emptied during the downstroke, and filled during the upstroke of the plunger, in a simple and eiective manner.

The particular kind of nozzle to be secured to the tube b, depends upon the particular kind of work to be performed by the machine. In Figs. l and 2, the tube b,hasadownwardly turned discharge end surrounded by avertically movable nozzle b. This nozzle is of tapering shape and is adapted to be closed by a fixed Valve d, the stem d', of which is rigidly secured to the pipe b.

During the descent of the plunger c, the dough, dsc., bears against the inner faceof the movable nozzle b', and draws the same down (Fig. 2), and away from the valve, while dur ing the ascent of the plunger, the suction will again draw the nozzle b', upward to close the same. Thus the nozzle is alternately opened and closed and is `particularly adapted for laying out all kinds of soft cakes, maearoons, sponge biscuits, meringues, the.

In Fig. 4, the nozzle e, is fixed and the valve e', is movable. The valve is depressed by hand and raised by a recoil spring e2. This nozzle is particularly adapted for laying out all kinds ot drops and confectionery.

In Fig. 5, the valve f, is normally closed by spring f', bearing against a hand lever f2, that is connected to the valve stern f3. This nozzle is used for making bonbons, chocolate centers, marshmallows and similar articles.

In Fig. 6, the nozzle g,is cup shaped and` provided with a serrated edge g. When the disk shaped plunger h, is lowered beneath the edge g', the dough is free to escape laterally, so as to form all kinds of jumbles, stars, hearts, rings and similar forms.

InFig. 7, a pointed nozzle i, is `:secured to the flexible hose 1l', and is used for the ornamentation of cakes with icing.

In Figs. 8 to l0, the nozzle j, has asharp V shaped cutting edge j', which is forced into the body of the cake. The filling which is ejected into the nozzle, will raise a light retaining spring 3'2, and be forced into the punctured cake.

It will be seen that with my machine `cakes and confectionery can be readily laid out, 3o decorated and filled ina very rapid, cleanly, uniform and economical manner, and without the employment of skilled labor.

l. The combination of a hopper with a 55 `tubular plunger, a perforated independently movable head having a pin that engages the plunger, an imperforate disk secured to the plunger above the perforated head; a discharge tube, a nozzle secured thereto and a valve adapted to engage said nozzle, substantially as speci tied,

2. rEhe combination of a hopper with a spring plunger, a disk secured thereto, a perforated independently movable head, an adjustable stop, and a cup-shaped `weight adapted to `embrace `the upper end of the plunger, substantiallyas specified.

3. The `combination .of a hopper with a 5o independently movable head, `a discharge tube, aconical `nozzle"rnovably secured thereto and a `fixed valve adapted .to .engage said nozzle, substantially as specitied.
